WAGON-DUMP.-

SPECIFICAVTION forming part of Letters Patent No. 431,678, dated .Tuly 8, 1890. Application led February 14, 1890. Serial No. 340,426. (No model.)

To all whom, it may concern: d

wn that I, ERNEST L. THoMs, a citi- Be it kno zen of the United States, residing at Ashby,

in the county of Grant and State of Minnesota, have inventedanew and useful Wagon- Dump, of which the following is a specification.

This invention relates to dumps for wagons; and the invention consists, broadly,in `a body mounted on a transverse shaft supported by the main framework, hinged supports beneath the rear end of said body, frictionwheels on said supportingshaft, frictionbands passing thereover, an operating-shaft journaled at the rear Vend of the frame-work, and chains or cords connecting said operatingshaft with both the supports and the frictionbands, aswell as in other arrangements of parts and details of construction, all as hereinaftermore particularly described.

In the accompanying drawings, Figure lis a centrallongitudinal section of myimproved dump. 'Fig'. 2 is a similar view showing the body in a dumped position. Fig, 3 is a rear elevation of the dump in the position shown in Fig. l.

The letter S designates the main supporting-shaft, which passes beneath the body B, preferably slightly in front of its center, and upon which said body is supported, the outer ends of said shaftbeing journaled in and supported by brackets s, rising from the framework F at either side, as will be readily understood. At thefront end of the frame-work a pair of studs fat either side thereof prevent the tilting down of the body at that end of the frame, and under the rear end of the body a pair of supporting-studs u are rigidly connected to a transverse bar U, which is hinged at its lower edge to the frame-work, as shown in Fig. 1, and which is adapted to hold the body in proper position when the upper ends of the studs are beneath the same, or to permit it to fall to its dumped position, Fig. 2, when said studs are moved backwardly from beneath it. Y

Upon the supporting-shaft S, and preferably at either side of the body B, is keyed a pair of friction wheels C, and over these wheels pass metallic strapse, which are connected at their rear ends to the frame-Work, vas shown, and at their forward ends to chains H, the latter passing thence under pulleys h and along the frame-work F at either side of the body B to drums D,'keyed upon an operating-.shaft O, which is journaled transversely in the frame. F at the rear of the body and provided with a handle Z at one end. Other chains H connect the upper ends of the supporting-'studs u with said drums D, as shown.

The parts being correctly assembled, the operation of my device is as follows: When it is desired to dump a wagon, it is driven onto the device wit-h its wheels resting on the body B, as shown, and the handle Z is turned upon in the proper direction, whereby a tension is imparted to the chain H. ends of the studs u are thereby pulled from beneath the rear end of the body B and the latter begins to descend; but just at this moment the continued revolution of the drums Dimparts' a tension to the chains H, result- The upper ing in a tightening of the metallic straps c upon the friction-Wheels O. As said wheels are keyed upon the supporting-shafts S, which is now turning with the body as the latter is tilting, the friction, which is caused by the drawing of said straps tightly against the faces of said friction-wheels, tends to retard the dumping operation to an extent only limited by the amount of tension imparted by the chains H. It will thus be seen that a wagon or cart containing one, or even two, tons may beA successfully dumped, and that in such a manner as to pour the load slowly from the tail of the Wagon-as, for instance, when it is desired to dump grain into a chute or into a trough leading to a cellar-window. The body is then returned to its normal position, as shown in Fig. l, and the cross-bar U IOO the boX can be turned on its supporting-shaft= studs u., hinged to thesame near its rear end, s

of the supporting-shaft S, journaled in said frame, the body mounted 0n the said shaft,

the friction-wheels C, keyed to said shaft` at each side of the box, the metallicstraps c,

passing around said wheels, and means, substantially asdescribed, for tripping said snpporting-studs and simultaneously imparting a tension `to said metallic straps, as and for the purpose described. y

3. In a Wagon-dump, the combination, with the stationary frame F, the standards s thereon, the shaft O, journaled. acrossfthe'reary end of said frame and having the crank-Z,-

and the drums D on said shaft, ofthe supporting-shaft S, journaled in ysaid standards, the body B, mounted on said shaft, `the `frictionwheels Q, keyed to said shaft at each side of the body, .the metallic straps c, secured to said frame and passing over said Wheels, and chains H, connectedto said straps, vpassing around pulleys h and connectedv to the drums D, substantially as and for the purpose set forth.

4. In a Wagon-dump, the combination, withl vthe stationary frame F, having standards s,

the supporting# shaft S, journaled in said standards, the body B, mounted on said shaft, the friction-Wheels C, keyed to said shaft at each side of the body, and means, substantially asdescribed, for imparting friction' to said wheels, of the transverse bar U, hinged t0 said frame under the rear end of said body, the supporting-studs u, projecting upward from said bar, the shaft O, journaled across the rear end of said frame and having the crank Z, the drums D on said shaft, and the Ichains H', connecting said drums With the upper ends of said studs, substantially as and for the purpose set forth.

5. In a Wagon-dump, the combination, with the main frame fF, the shaft O, 4journaled across therear end thereof and having a crank Z, andthe drums D on said shaft, of the body B, mounted enla supporting-shaft S, j ournaled in said frame', friction-wheels C, keyed to said shaft at each side of the box, metallic straps c, passing around said friction-wheels, and chainsH, leading from the front ends of said metallic straps under pulleys z. and to the drums D, the cross-bar U, hinged to said frame, the upwardly-extending studs u, carried thereby andv supporting the rear end of the body, and the chains I-I, connecting said stu'ds with said drums, the connections being such that'the rotation of the drums will first trip the studs and then immediately apply the brake-straps c, as and for the purpose set forth.

In testimony that vI claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses. V
